What Is Sony Ericsson Unlocking?
When you purchase a Sony Ericsson K770 phone from a network carrier, it may
be locked to that carrier so it works only with their specific SI card.
The only reason to lock the phone is to ensure you use their service for an
extended period of time. If you attempt to use an alternative SI card in a
locked phone, you will receive an error message such as "Wrong SI Card".
Cell phone unlocking enables you to use your mobile phone with a SI card
from any carrier. Once the device is unlocked, the error message is removed
and you are free to use the SI card of your choice.
Unlock Metho :
Our I EI based unlocking is reliable and safe. It requires that you provide your
I EI number (press *#06# on your device) to us so that we can calculate the
unlock code. Once the code is ready, enter it with our unlock instructions. It
will never relock, even if you wipe or update the firmware.
Unlocking Benefits:
There are many benefits to unlocking your Sony Ericsson K770 phone,
including:
•Ability to use any SI card from any network
•Save money by choosing the cheapest available carrier
•Switch to a carrier that offers better service
•Travel and use cheap local SI cards rather than your native SI card,
thereby avoiding high roaming fees
•ake money by selling your phone unlocked (unlocked phones have a
higher resale value than locked phones)
